Interkosmos is a musical documentary-style film about the East German space program-a program with the energy and creativity of the Soviet arts scene of the 1920s and a bit of the hippie sensibility from West Germany of the early 1970s. The story is about a failed space colonization mission called "wundertüte" and is told through narration, dialogue, letters, and period songs.
